Answer:
Protein.
Explanation:
In the image above, we see a molecule that is made up of several amino acids. The molecule that is made up of amino acids is protein.
Proteins are the most abundant organic macromolecules in cells, fundamental to cell structure and function. They are found in all cell types and viruses.
They are formed by amino acids linked together and joined by peptide bonds, as shown in the image above.
Of extremely high molecular weight, proteins are composed of carbon, hydrogen, nitrogen and oxygen, practically all of them have sulfur. Elements such as iron, zinc and copper may also be present.
All proteins are made up of a set of 20 amino acids, arranged in varying specific sequences.
